Hi,

We have a few projects and some of these projects share code "libraries". Some of which are persistent classes that are used by multiple systems. All these are currently deployed on Ensemble. We want to move some of the smaller ones to the cloud and make use of IRIS.

The challenge is that once we synchronise the code to IRIS from Atelier, then IRIS changes the storage definitions, which then creates changes to the files. We do not want to commit all these changes to git as it will happen again once someone synchronises with Ensemble.

I want to do some logic based on what environment code is running in. I can't find a built-in function to retrieve this so I'd like to write a custom function. Does anyone know of a command that would get the current environment?

Here is the function I'm writing:

For some reason when I try to run it I get the following error:

 set sc1 = Lookup("ParticipantCodeMap",a)
 ^
<UNDEFINED> 

I tried adding the the default parameter in case it's not finding it but it didn't help.  What am I missing?

I just downloaded and installed the latest WebTerminal into my local copy of Healthshare 2016.2.1

I installed via studio and everything compiled without error.

However when I run it I just see a black screen. The help window at the bottom of the screen pops open when I type '/' but I just can't get any response.

Any suggestions as to how to trouble shoot this?

Hello everyone,

I want to fill data into my select component with sql request and parameter.

I tried to follow this example https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KE…;

I need to call a method because my parameter can be different. I tried something like this but it doesn't work... 

 ClientMethod changeParams() [ Language = javascript ]
{


var query = zenPage.getComponentById('categorieBeneficiaire');
query.setProperty('parameter', 1, 'OS');

Hello all...

Is there two matching patterns in Caché, is there a difference in use one or the other?
Example:

USER>set a = "(1234)"

Using $match.

USER>w $match(a,"\([0-9]{4}\)")

USER>1

Using literal match (sorry if not correctly term expression)

USER>W a?1"("4n1")"

USER>1

What is different from using one or the other?

The 'a?1"("4n1")"' does this pattern exist only Caché.
Exists performance improvement with use pattern Caché?

I can directly order over a MultiDimensional property, e.g.

set key=$order(obj.prop(key))

However I have a generic method that has to use the $property method, if I know the keys then I can just fetch a value with...

set value=$property(obj,"prop","key")

But if I don't know the keys then I am not aware of a solution to do this, e.g.

set key=$order($property(obj,"prop",key))

will not work.

There must be an internal solution as a zw command on obj is able to list all of the keys. I'm wondering if there is a $zu function or other trick that can do this. Any ideas?

Thanks,
Sean.

The phone number field for the PID segment was customized to send email address in PID 13.4. How can I remove the email address to map only the phone number to the PID 13.1 field?

Recently, a partner company started to develop an Angular client for their Cache application. Together, we decided to leverage the power of Caché dynamic objects to exchange JSON encoded data between client and server parts. However, we realized that currently there is a gap in Cache JSON implementation that prevents simple use of traditional registered and persistent classes to exposed their data with the same ease as with XML. I wrote a small JSON adapter, that does the job and bridgers the gap. It's purpose is simple expose data described by a regular Cache class in a one-to-one fashion to a %DynamicObject. On the other hand, when a serialized JSON data comes in, it can be easily deserialized into dynamic object and subsequently bound to regular class by the newly created adapter.

I think I already know the answer to this but I thought I'd ask anyway. So the Node.js adapter allows you to perform operations directly on Globals. Does the InterSystems.Data.CacheClient.dll or InterSystems.CacheExtreme.dll provide a mechanism to access Gobals directly or are you accessing globals via Caché ObjectScript classes?

This code snippet uses %ZEN.Auxiliary.jsonSQLProvider. The namespace and string of SQL can be edited for different situations. The class method "test" runs the code:

Class eduardlebedyuk.passQuestionParams
{
classmethod test(pValue = 50) {
s ns = $Namespace
zn "samples"
s tSQL = "SELECT ID, Name FROM Sample.Person WHERE Id > ?"
s tPR = ##class(%ZEN.Auxiliary.jsonSQLProvider).%New()
s tPR.sql = tSQL
s tPR.%Format = "tw"
s tPR.maxRows = 100
    s tParam = ##class(%ZEN.Auxiliary.parameter).%New()
    s tParam.value = pValue
    d tPR.parameters.SetAt(tParam,1)
  
    d tPR.%DrawJSON() 
    //d ##class(%ZEN.Auxiliary.jsonSQLProvider).%WriteJSONFromSQL(,,,,,tPR)  //same thing
    zn ns
}

}

I would like that the file name will be a parameter that will be set by code and not hardcoded as in the image below

Thanks 

I have a ZEN page with nine tablepanes. Each tablepane queries a table in the same SQLServer db. I have a single SQLGateWay(odbc) to this SQLServer db. I need to get better performance when I query all nine table at the same time. Would my performance improve if I had nine SQLGateWays(nine odbc configurations/connections), one for each query? I would appreciate any and all suggestions for getting the very best performance when using SQLGateWays. Thank you.

I have created a view to stage some data in a different format and then want to reference that view in a SQL query from a table that filters the data from the view using a property of the table. 

Example:

select
   MsgId,
   FileName,
   (select
      ReportName
     from
      custom_view
     where
       MsgId = ReportId
    ) as ReportName
from
   main_table

Is this even possible? When I try this, I get an error table not found for the view?

All responses are appreciated.  I am new to both scripting and CACHE so please bear with me.  I am setting up a nightly backup script for freezing cache then backing it up and then thawing it back out.  Currently when I enter the freeze command I am getting a response of access denied even though my id has %all access.  I've tried passing the userid/password as a parameter in the externalfreeze command and passing it from a file.  I've used my id and lastly I used the _system id in the file.  What ID should I use for this or am I passing it wrong?

sample 1:  .

Is there a way to use linked tables between 2 discrete Cache databases or is linked tables just for access to an external RDBMS?

Hello, our Team is trying to develop Ensemble DTL to transform incoming X12 files into persistent data records. We created a persistent class and we can insert data using SQL. We tried to verify that %Save() gets called by adding %AddToSaveSet() method to persistent class and there writing to a global. We had to extend our persistent class with Ens.VDoc.Interface class or we could not see %Save() being called from Ensemble DTL. We suspect that %Save() gets some kind of error. We tried to debug by overwriting Transform() method in our DTL class.

All,

Recently, a Cache 2017.2.2  system started printing “28”  rather than clearing the screen when doing a  “W #”  in programmer mode.

Does anyone have any idea how this could happen?

This should clear the screen, but doesn't:

XXXX:YYYY>W #
28

I would like to know how to choose the "Development" installation type in silent mode.

When performing a normal installation:

Please review the installation options:
------------------------------------------------------------------
Instance name: CACHE
Destination directory: /cache
Cache version to install: 2015.2.1.705.0.17420
Installation type: Development

When I perform a silent install:

Please review the installation options:
------------------------------------------------------------------
Instance name: CACHE
Destination directory: /cache
Cache version to install: 2015.2.1.705.0.

Hi,

I ran the Cache ODBC Driver installer as Administrator on my Windows 7 PC this morning. It completed successfully with o indication of any issues. When I check installed programs and features via Win 7 Control Panel, I see it listed as Intersystems ODBC Driver 1.00.000.

However, when I try to configure the driver via Control Panel - Administrative Tools - Data Sources (ODBC), I cannot find it. The only driver listed under the Drivers Tab is SQL Server.

I am not sure how to proceed.

I appreciate any suggestions.

Thanks,

Bill

In our language we have scandic letters like ä (a with two dots on it).

In Angular we use login like this:

let headers = new Headers();

password = Base64.fromBase64(password);

headers.append('Authorization', 'Basic ' + Base64.encode(username + ':' + password));

let options = new RequestOptions({ headers: headers, withCredentials: true });

return this._http.get(_param.baseUrl + this._loginUrl, options)

.map((res: Response) => {

It works, but not with these letters.

Hi All,

I need some help with sending PDF files to printer using cache instead of using third party tools(Adobe, foxit reader, etc..).
Sometime i getting access issue with the exe files.

Can able to send text data to printer using below code.

Set Dev="|PRN|PrinterName"
OPEN Dev:(/DATATYPE="TEXT"):80
USE Dev Write "Test printing",!
CLOSE Dev

Any suggestions on sending PDF to printer?

Method1(){

Set OID1=##class(Table).%OpenId(100)

// do Kill OID

}

&SQL(Update Table Set  Column=88)

Method2(){

Set OID2=##class(Table).%OpenId(100)

// Or do %Reload()

Set OID.Column=99

Do OID.%Save()

}

// Column 1 still holds value as 1

For getting the updated value I should do Kill OID in Method1

Hi, 

My administrator was wondering where %SYS/ZAUTHENICATE.mac is stored?

He preforms a nightly backup, and would like to include the custom ZAUTHENTICATE.mac that was written for our Delegated/LDAP configuration.

It's well-known that namespace global mapping helps us to write code independent on database storage details (Caché instance name, directory path). But sometimes we can face problems accessing an unsubscripted global which has subscript level mapping (SLM) defined. Most of such cases are evident and associated with administrative tasks that should be done on database level, but some of them can confuse even an experienced developer. Just to start:

• We can't export such a global using Caché Block format (a.k.a. GOF).
• We can't kill such a global.

Maybe you can continue this list.
